To all whom it may concern.-

Be it known that I, FRANZ BURGER, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Gas or Vapor Engines, of which the following is a specification.

My invention is a motor having two mom hers, one or both of which may rotate, one of said members being a casing and the other consisting of one or more tubes, with means for causing the propulsive discharge of gases from the end of each tube, whereby to rotate one member by direct propulsion or the other by reaction, as fully set forth hereinafter and illustrated in the accompanying drawings, in WhlGh- 1 Figure 1 is a sectional elevation of my improved engine, and Fig. 2 is a sectional plan.

The engine has a member A, consisting, of a casing 4, and another member B, consisting of one or more tubes 3, each open at one end, and, as shown, a shaft 1 supports the member 13 and extends through the member A. The shaft 1 is provided with a wheel 2, to which are fastened tangentially the cylinders or tubes 3. The tubes 3 are closed at one end and open at the other end. These tubes revolve in the casing 4, which is provided on the inside with an annular chamber 5, into which the exhaust passes and from which it is carried away through the exhaust-opening 6 into the atmosphere, The two covers '7 and 7, on each side, inclose the revolving parts nearly to the shaft 1, where an opening 8 on each side of the wheel is left, through which pass the primary and also the secondary wires to the insulated rings 9 and 10. The circuit to the ring 9 is primary and that to the ring 10 is secondary. To the inside rim 13, which with the casing forms the annular chamber 5,.

are cast the stationary diverging blades or partitions 11, projecting toward the revolving cylinders 3 without touching the same.- The channels between the partitions 11 communicate by the ports 12 with the annular chamber 5. Near the bottom of each cylinder are placed the inwardly-opening valves 14, closing the side ports 15. In these ports 15 are also located the fueLsupply pipes 16, which also are closed at their outer ends by the valves let. The other ends of the supply-pipes 16 extend to the transverse port 17 of the shaft 1, which port communicates with the longitudinal hole 18 in the shaft 1, to which leads the stationary fuel-supply pipe 20. The fuel-for instance, gasolene-in this pipe is under a light pressure.

The valves 14 are each hinged at 2t and are provided with an extending counterweight 22,

which is placed at such an angle as to counterbalance the centrifugal force on the valve 14. This could also be accomplished by suit able springs.

The valves 1% are provided with laps or extensions 23,which make contact with two electrodes 24: and 25, which in turn connect through the rings 9 with a battery 26 and the induction-coil 27. WVhen the valves 1.4 are 011 their seats, the circuit is closed and a jump ing spark from the induction-coil 27 will pass between the two porcelain insulated points 28, firing the mixture in the two cylinders. The current is transmitted by the conductors 29 and 30 to the two rings 10 and from there to both cylinders. By this method a continuous succession of sparks will jump across at the point 28 in each cylinder as long as the valve l4c thereof is closed.

The operation of this engine is as follows:

then be turned by hand to a point where the 0 valve 14:, above referred to, will automatically close, and thereby close the primary circuits at and 25, and thereby produce a jumping spark between the points 28, which will fire the explosive mixture in the cylin- 9 5 der and thus start the engine. The pressure created at this instant drives out the air or gases with great velocity against the stationary partitions and by reaction drives the tubes 3, and with them the wheel 2, in the too opposite direction, When the first explosion has occurred, the next charge enters the cyl- There will necesinders automatically, because when the explosion has occurred the gases contained in the long cylinders are ejected with great velocity, and thus and also by condensing a partial vacuum is formed at the bottom of each cylinder, which lifts the valve, and a new charge, composed of air and gas or vapor, enters the cylinder. When the equilibrium is established, the valve will seat, closing the electric circuit, and thereby again establish the circuit and cause an ignitingspark.

It will be seen that no internal resistance to the movements of the engine can exist and that as there is no piston to propel no internal lubrication is required; also, that no water is needed, asthe heat developed from the explosion can do no harm.

Without limiting myself to the precise construction and arrangement shown I claim- 1. The combination in a motor, of two members one of which is rotatable and one being a casing and the other a tube, the tube being open at one end and provided near its closed end with a passage for the admission of an explosive mixture, a pair of electrodes in a spark-producing circuit supported adjacent to said passage, and a movable valve for controlling said passage and also the circuit through said electrodes, substantially as set forth.

2. The combination in a motor, of two members one of which is rotatable, and one being a casing and the other a tube within the casing, the tube being open at one end and provided near its closed end with a passage for the admission of an explosive mixture, a valve within the tube movable to open and close said passage, and a pair of electrodes in a spark-producing circuit supported by said tube to be engaged .by said valve when the latter is in position to close said passage, substantially as set forth.

3. In a motor, the combination of a fixed easing, a rotatable shaft extending centrally through the casing, a plurality of tubes supported by said shaft tangentially thereto,

each tube being open at one end and pro- I FRANZ BURGER. \Vitnesses:
